It is an object of the present invention to provide compounds which reduce the disadvantages of using the abovementioned herbicides of the formulae II and III at least to such an extent that the yield of the crops at harvest is no longer reduced or not significantly reduced.

We have found that this object is achieved by the agents defined at the outset.

We have also found methods for the combined treatment of crops with the antidote compounds I on the one hand and the herbicides II and/or III on the other hand, whether the herbicidal active ingredient and the antidote compound are formulated and applied together or separately or, in the case of separate application, the order in which the herbicidal active ingredient and the antidote are applied being unimportant.

Derivatives I having acidic terminal groups or having basic nitrogen atoms may be in the form of their agriculturally useful salts.

Suitable acid addition salts are the salts of acids which do not adversely affect the antidote action of I, for example the hydrochlorides, hydrobromides, sulfates, nitrates, phosphates, oxalates or dodecylbenzenesulfonates.

Suitable basic salts are the salts of bases which do not adversely affect the antidote action of I, for example the alkali metal salts, in particular the sodium and potassium salts, the alkaline earth metal salts, in particular the calcium, magnesium and barium salts, transition metal salts, in particular manganese, copper, zinc and iron salts, ammonium salts which may carry from one to three C₁ -C₄ -alkyl or hydroxy-C₁ -C₄ -alkyl substituents and/or a phenyl or benzyl substituent, in particular diisopropylammonium, tetramethylammonium, tetrabutylammonium, trimethylbenzylammonium and trimethyl-(2-hydroxyethyl)-ammonium salts, the phosphonium salts, sulfonium salts, in particular tri-C₁ -C₄ -alkylsulfonium salts, and the sulfoxonium salts, in particular tri-C₁ -C₄ -alkylsulfoxonium salts.

The substituted 2-aminothiophenes of the formula I are obtainable by various methods, preferably by one of the following processes:

a) Condensation of a ketone XI with sulfur and an acetonitrile derivative XII to give a substituted 2-aminothiophene Ia: ##STR10##

The reaction is carried out in general in a conventional manner [cf. K. Gewald et al., Chem. Ber. 99 (1966), 94 and E. F. Elslager et al., J. Heterocycl. Chem. 9 (1972) 775] in an inert solvent or diluent, for example in an alcohol, such as methanol, ethanol, n-propanol and isopropanol, in an ether, such as dioxane and tetrahydropyran, in a nitrile, such as acetonitrile and propionitrile, in an aprotic solvent, such as dimethylformamide, dimethyl sulfoxide and N-methylpyrrolidone, or in an excess of the ketone XI.

The reaction can also be carried out using a phase transfer catalyst, such as trioctylpropylammonium chloride and cetyltrimethylammonium chloride, in a 2-phase system of water and a hydrocarbon, e.g. carbon tetrachloride [cf. Synthesis (1974) 867].

The reaction is preferably carried out in the presence of an inorganic or organic base.

Examples of suitable bases are alkali metal hydroxides, such as sodium hydroxide and potassium hydroxide, alkaline earth metal hydroxides, such as calcium hydroxide, alkaline earth metal alcoholates, such as sodium methylate, sodium ethylate, potassium ethylate and potassium tert-butylate, alkaline earth metal alcoholates, such as a calcium alcoholate, alkali metal hydrides, such as sodium hydride and potassium hydride, alkaline earth metal hydrides, such as calcium hydride, aliphatic amines, such as dimethylamine, triethylamine and diisopropylamine, dimethylaniline, dimethylbenzylamine, piperidine and heteroaromatic amines, such as pyridine and 4-dimethylaminopyridine.

In the case of the amines, the reaction can also be carried out in an excess of base, in the absence of a solvent.

All reactants are advantageously used in stoichiometric amounts, but it is also possible to use an excess of up to about 10 mol % of one or other component.

If the base is used as the solvent, it is present in a large excess.

In general, the reaction temperature is from 0° to 200° C., preferably from 20° to 140° C., in particular at the boiling point of the relevant solvent.

The reaction is usually carried out at atmospheric pressure or at the autogenous pressure of the solvent used.

Other possible methods of synthesis comprise reacting α-mercaptoketones with acetonitrile derivatives XII having an active methylene group [cf. K. Gewald, Chem. Ber. 98 (1965), 3571].

b) The reaction of substituted 2-aminothiophenes Ia with an electrophilic compound XIII to XVIII: ##STR11## Hal is chlorine or bromine.

The reactions are usually carried out by conventional processes in an inert solvent or diluent in the presence of a base:

for the reaction of Ia with carbonyl halides or anhydrides to give amides or imides, respectively, see Henecka in Houben-Weyl, Methoden der Organischen Chemie, Volume 8, pages 653-713;

for the reaction of Ia with sulfonyl chlorides to give sulfonamides, see Mutz in Houben-Weyl, Methoden der Organischen Chemie, Volume 9, pages 599-658;

for the reaction of Ia with iso(thio)cyanates to give (thio)ureas, see Petersen in Houben-Weyl, Methoden der Organischen Chemie, Volume 8, pages 129-136;

for the reaction of Ia with aromatic aldehydes to give Schiff bases, see Freytag in Houben-Weyl, Volume 11/2, pages 73-98.

Examples of suitable solvents are aliphatic hydrocarbons, such as n-hexane, gasoline and petroleum ether, aromatic hydrocarbons, such as benzene, toluene, and o-, m- and p-xylene, chlorohydrocarbons, such as dichloromethane, chloroform, tetrachloromethane, 1,2-dichloroethane and chlorobenzene, nitrogen-containing heteroaromatics, such as pyridine and quinoline, cyclic ethers, such as tetrahydrofuran and dioxane, nitriles, such as acetonitrile and propionitrile, and dimethylformamide, dimethyl sulfoxide and N-methylpyrrolidone, or a mixture of the stated solvents. In the presence of a phase transfer catalyst, the reaction can also be carried out in a 2-phase system of water and a hydrocarbon, e.g. carbon tetrachloride.

Regarding the bases and phase transfer catalysts which can be used, the ratios and the pressure, the data given for method (a) are applicable.

In general, the reaction temperature is from 0° to 200° C., preferably from 20° to 140° C., in particular the boiling point of the relevant solvent.

The electrophilic compounds XIII to XVIII are known or are obtainable by known processes (cf. Sustmann in Houben-Weyl: Methoden der Organischen Chemie, Volume E5, 590-608 and 634-652). The educts XVIa and XVIb are advantageously prepared in situ from halosulfonyl isocyanates and reactive compounds R¹¹ -H and the compounds XVIIa and XVIIb are prepared in a similar manner from isocyanate salts, such as ammonium isocyanate and compounds Hal--CY--R⁸.

The substituted 2-aminothiophenes I are suitable as antidotes for increasing the toleration of herbicidal active ingredients by crops such as millet, rice, corn, cereals (wheat, rye, barley and oats), cotton, sugar beet, sugar cane and soybean. They have an antagonistic effect on herbicides of a very wide range of classes, such as triazines, phenylurea derivatives, carbamates, thiocarbamates, haloacetanilides, benzoic acid derivatives and in particular halophenoxyacetic esters, substituted phenoxyphenoxyacetic esters, phenoxyphenoxypropionic esters and cyclohexenone derivatives.

R⁴ is phenyl, pyridyl, benzoxazyl, benzothiazyl or benzopyrazinyl, where these aromatic ring systems may carry up to two of the following radicals: halogen, nitro, C₁ -C₄ -alkyl, C₁ -C₄ -haloalkyl and/or C₁ -C₄ -haloalkoxy;

R^(b) is hydrogen, C₁ -C₄ -alkyl or one equivalent of a plant-tolerated cation and

are disclosed in the literature, for example in DE-A-22 23 894, DE-A-24 33 067, DE-A-25 76 251, DE-A-30 04 770, BE-A-868 875 and BE-A-858 618.

They are used for controlling undesirable plants from the Gramineae family. However, the toleration of these substances by crops varies from commercially acceptable to non-tolerated, depending on the substituents and the application rate.

The same applies to cyclohexenone derivatives of the formula III ##STR13## where

R^(d) is C₁ -C₄ -alkyl which [lacuna] methyl, ethyl, n-propyl, isopropyl, n-butyl and tert-butyl, preferably ethyl and n-propyl;

R^(e) is C₁ -C₄ -alkyl, such as methyl, ethyl, n-propyl, isopropyl, n-butyl and tert-butyl, preferably ethyl or n-propyl, C₃ - or C₄ -alkenyl, preferably prop-2-enyl, C₃ - or C₄ -alkynyl or C₃ - or C₄ -haloalkenyl, preferably 3-chloroprop-2-en-1-yl,

a C₁ -C.sub. 4- alkylene or C₂ -C₄ -alkenylene chain, both of which may furthermore carry from one to three C₁ -C₃ -alkyl radicals and/or halogen atoms, or a 3-membered to 6-membered alkylene or 4-membered to 6-membered alkenylene chain which may be substituted by C₁ -C₃ -alkyl and each of which contains as a chain member an oxygen or sulfur atom not directly adjacent to the oxime ether moiety, all abovementioned chains carrying as a terminal group the phenyl ring which in turn may be substituted by from one to three radicals selected from the group consisting of a benzyloxycarbonyl or phenyl radical and from one to three of each of the following radicals:

nitro, cyano, halogen, C₁ -C₄ -alkyl, C₁ -C₄ -alkoxy, C₁ -C₄ -alkylthio, partially or completely halogenated C₁ -C₄ -alkyl, partially or completely halogenated C₁ -C₄ -alkoxy, carboxyl and C₁ -C₄ -alkoxycarbonyl, and it being possible for the phenyl ring additionally to carry a number of halogen atoms such that the total number of radicals is 4 or 5; 4-(p-fluorophenyl)-but-3-enyl, 4-(p-chlorophenyl)-but-3-enyl and 2-(p-chlorophenoxy)-propyl are particularly preferred;

thienyl which may carry a halogen atom;

R^(f) is C₁ -C₄ -alkyl as stated for R^(d), which may be monosubstituted or disubstituted by C₁ -C₄ -alkylthio or by C₁ -C₄ -alkoxy,

a 5-membered or 6-membered saturated or monounsaturated ring system which, in addition to carbon members, may contain an oxygen or sulfur atom or a sulfinyl or sulfonyl group, preferably tetrahydropyranyl, dihydropyranyl and tetrahydrothiopyranyl, where the ring system may carry from one to three radicals selected from the group consisting of hydroxyl, halogen, C₁ -C₄ -alkyl, C₁ -C₄ -haloalkyl, C₁ -C₄ -alkoxy and C₁ -C₄ -alkylthio,

a 10-membered saturated or monounsaturated heterocyclic structure which contains two nonadjacent oxygen atoms or sulfur atoms and may be substituted by up to three C₁ -C₄ -alkyl groups and/or methoxy groups, or

phenyl, pyridyl, thiazolyl, pyrazolyl, pyrrolyl or isoxazolyl, where each of these groups may carry from one to three radicals selected from the group consisting of: C₁ -C₄ -alkyl, C₁ -C₄ -haloalkyl, C₁ -C₄ -alkoxy, C₁ -C₄ -alkylthio, C₃ -C₆ -alkenyloxy, C₃ -C₆ -alkynyloxy, C₁ -C₄ -alkoxy-C₁ -C₃ -alkyl, C₁ -C₄ -dialkoxy-C₁ -C₃ -alkyl, formyl, halogen and benzoylamino;

R^(g) is hydrogen or hydroxyl or, when R^(f) is C₁ -C₆ -alkyl, is C₁ -C₆ -alkyl, preferably hydrogen;

R^(h) is hydrogen, cyano, halogen, C₁ -C₄ -alkoxycarbonyl or a C₁ -C₄ -alkylketoxime group, preferably hydrogen;

R^(i) is hydrogen or one equivalent of an agriculturally useful cation.

They are also described in the literature (e.g. EP-A 228 598, EP-A 230 235, EP-A 238 021, EP-A 368 227, U.S. Pat. No. 4,432,786, DE-A 24 39 104, DE-A 40 14 986 and DE-A 40 33 423) as herbicides and are used predominantly for controlling undesirable grasses in dicotyledon crops and in grasses which do not belong to the Gramineae family. Depending on the structure of the substituents and the dose used, compounds of this group can also be used for selectively controlling undesirable grasses in gramineous crops such as wheat and rice.

Cyclohexenone derivatives of the formula III in which R^(e) is an unsubstituted or substituted alkylphenyl or alkenylphenyl radical, e.g. butyl- or butenylphenyl, can be prepared in a conventional manner from already known derivatives of the formula IV (EP-A 80 301, EP-A 125 094, EP-A 142 741, U.S. Pat. No. 4,249,937, EP-A 137 174 and EP-A 177 913) and the corresponding hydroxylamines of the formula V (Houben-Weyl, 10/1, page 1181 et seq.) (EP-A 169 521). ##STR14##

The reaction is advantageously carried out in the heterogeneous phase in a solvent at a sufficient temperature below about 80° C., in the presence of a base, and the hydroxylamine V is used in the form of its ammonium salt.

Examples of suitable bases are carbonates, bicarbonates, acetates, alcoholates or oxides of alkali or alkaline earth metals, in particular sodium hydroxide, potassium hydroxide, magnesium oxide and calcium oxide. Organic bases, such as pyridine or tertiary amines, may also be used. The base is added, for example, in an amount of from 0.5 to 2 mol equivalents, based on the ammonium compound.

Examples of suitable solvents are dimethyl sulfoxide, alcohols, such as methanol, ethanol and isopropanol, aromatic hydrocarbons, such as benzene and toluene, chlorohydrocarbons, such as chloroform and dichloroethane, aliphatic hydrocarbons, such as hexane and cyclohexane, esters, such as ethyl acetate, and ethers, such as diethyl ether, dioxane and tetrahydrofuran. The reaction is preferably carried out in methanol using sodium bicarbonate as the base.

The reaction is complete after a few hours. The product can be isolated, for example, by evaporating down the mixture, partitioning the residue in methylene chloride/water and distilling off the solvent under reduced pressure.

However, it is also possible to use the free hydroxylamine base directly, for example in the form of an aqueous solution, for this reaction; depending on the solvent used for the compound IV, a one-phase or two-phase reaction mixture is obtained.

Examples of suitable solvents for this version are alcohols, such as methanol, ethanol, isopropanol and cyclohexanol, aliphatic and aromatic hydrocarbons and chlorohydrocarbons, such as hexane, cyclohexane, methylene chloride, toluene and dichloroethane, esters, such as ethyl acetate, nitriles, such as acetonitrile, and cyclic ethers, such as dioxane and tetrahydrofuran.

Alkali metal salts of the compounds III can be obtained by treating the 3-hydroxy compounds with sodium hydroxide, potassium hydroxide or a sodium or potassium alcoholate in aqueous solution or in an organic solvent, such as methanol, ethanol, acetone or toluene.

Other metal salts, such as manganese, copper, zinc, iron, calcium, magnesium and barium salts, can be prepared from the sodium salts in a conventional manner, as can ammonium and phosphonium salts, by means of ammonia or ammonium, phosphonium, sulfonium or sulfoxonium hydroxides.

The compounds of type IV can be prepared by known methods (Tetrahedron Lett. (1975), 2491), for example from the corresponding cyclohexane-1,3-diones of the formula VI ##STR15## where Z is hydrogen or methoxycarbonyl and R^(g) is hydrogen.

It is also possible to prepare the compounds of the formula IV via the enol ester intermediates, which are obtained in the reaction of compounds of the formula VI with acyl chlorides in the presence of a base and are then subjected to a rearrangement reaction with certain imidazole or pyridine derivatives (Japanese Preliminary Published Application 79/063 052). ##STR16##

The compounds of the formula VI are obtained by a number of known process steps, starting from known intermediates.

The hydroxylamines V in which R^(e) is unsubstituted or substituted phenylbutyl are synthesized according to the reaction scheme below, for example via

A) alkylation of cyclic hydroxyimides VII with suitable phenylbutyl halides and subsequent elimination of the protective group, for example with hydrazine or ethanolamine, similarly to Examples from EP-A-244 786 or Houben-Weyl, Methoden der organischen Chemie, Volume X/1, page 152 et seq.

B) Hydrogenation of N-4-phenylbutenyloxyphthalimides, whose preparation is described in DE-A 38 38 310, by means of suitable catalysts, e.g. palladium on active carbon, in suitable inert solvents, such as methanol, tetrahydrofuran or dioxane, and subsequent elimination of the protective group as described above.

The hydrogenation is advantageously carried out at 20° C. to the boiling point of the solvent, in particular at room temperature, by a conventional method, at atmospheric, superatmospheric or reduced pressure. A pressure range of from 1 to 10, in particular from 1 to 2, bar is preferred. ##STR17##

Examples of suitable cyclic hydroxyimides VII are the following substances: ##STR18##

The synthesis of the hydroxylamines V in which R^(e) is unsubstituted or substituted butenylphenyl, where the phenyl radical abbreviated to Ph below may in turn be substituted or unsubstituted, is carried out according to the reaction scheme below, by diazotization of aniline derivatives and subsequent coupling of the diazonium salt to a correspondingly substituted butadiene VIII. The resulting mixture IXa and IXb is coupled to a cyclic hydroxyimide XI, and the resulting protected hydroxylamine derivative X is cleaved with 2-aminoethanol to give the free hydroxylamine V: ##STR19##

R^(j), R^(k) and R^(l) independently of one another are each hydrogen, C₁ -C₃ -alkyl and/or halogen. Hal is halogen, preferably chlorine.

The halides IXa required for the above synthesis of the hydroxylamines V can be prepared, as a mixture with IXb, by processes known from the literature, for example by reacting diazonium salts of aromatic and heteroaromatic anilines with dienes. The range of use of the reaction is discussed in Organic Reactions 11 (1960), 189 and ibid. 24 (1976), 225.

Coupling of the isomeric halides IXa and IXb to a cyclic hydroxyimide of the formula VII gives exclusively the cyclic imido ethers of the formula X which, after elimination of the protective group on the nitrogen, give the hydroxylamines V.

The reaction with a hydroxyimide VII (Routes a and c) is carried out in the presence of an acid acceptor and of a solvent. For cost reasons, hydroxyphthalimide is preferably used as the hydroxyimide VII.

Suitable acid acceptors are alkali metal carbonates, such as potassium carbonate or sodium carbonate, alkali metal bicarbonates, such as potassium bicarbonate and sodium bicarbonate, tertiary amines, such as trimethylamine and triethylamine, and basic heterocycles, such as pyridine. For cost reasons, potassium carbonate and sodium carbonate are preferred.

Suitable solvents are aprotic dipolar organic solvents, e.g. dimethylformamide, dimethyl sulfoxide and/or sulfolane.

Alkylation under phase transfer conditions is also possible. Water-immiscible compounds, such as hydrocarbons or chlorohydrocarbons, are used here as organic solvents. Suitable phase transfer catalysts are quaternary ammonium and phosphonium salts.

The cleavage of the cyclic imido ethers X is carried out similarly to a process described in EP-A 244 786, using an alkanolamine. In this process, the hydroxylamines V can be isolated as free bases or, after precipitation with acids, as salts. Readily crystallizing salts are obtained by reacting the bases with oxalic acid.

The specific examples of herbicidal (hetaryloxy)- and aryloxyphenoxyacetic acid derivatives of the formula II whose toleration by crops can be improved by substituted 2-aminothiophenes I are shown in Table 1 below.

Herbicidal active ingredients and antidote compounds can be applied together or separately, after emergence, to the leaves and shoots of the crops and of the undesirable grasses. The antidote is preferably applied simultaneously with the herbicidal active ingredient. Separate application, where the antidote is first applied to the field and then the herbicidal active ingredient, is also possible. The herbicidal active ingredient and the antidote can be formulated together or separately as a spray in suspendable, emulsifiable or soluble form.

Antidote effects are also achieved by treating the seeds of crops or the seedlings with the antidote before sowing or before planting out. The herbicidal active ingredient is then applied alone in the conventional manner.

In the treatment of seeds, in general from 0.1 to 10 g, preferably from 1 to 2 g, of active ingredient are required per kilogram of seed.

In the application of the antidote by seed swelling or in the treatment of seedlings, solutions which contain the antagonistic active ingredient in a concentration of from 1 to 10,000 ppm, in particular from 100 to 10,000 ppm, are preferably used.

Different amounts of an antidote compound are required for herbicidal (hetaryloxy)- or aryloxyphenoxyacetic acid derivatives II if the herbicide is used in different crops. The ratios can be varied within wide ranges. They are likewise dependent on the structure of the (hetaryloxy)- or aryloxyphenoxyacetic acid derivatives and on the particular target crop. Suitable weight ratios of herbicidal active ingredients to antidote compound are from 1:10 to 1:0.01, preferably from 1:4 to 1:0.1.

Different amounts of an antidote compound are required for the same cyclohexenone derivative III if the latter is used in different crops. The ratios in which the cyclohexenone derivative and a substituted 2-aminothiophene I are used can be varied within wide ranges. They are dependent on the structure of the cyclohexenone derivative and of the substituted 2-aminothiophene I and on the particular crop. Suitable weight ratios of herbicidal active ingredient to antidote compound are from 1:10 to 1:0.01, preferably from 1:4 to 1:0.25.

The novel agents or, in the case of separate applications, the herbicidal active ingredients or the antidote are applied, for example in the form of directly sprayable solutions, powders, suspensions, including concentrated aqueous, oily or other suspensions, or dispersions, emulsions, oil dispersions, pastes, dusting agents, broadcasting agents or granules, by spraying, atomizing, dusting, broadcasting or pouring. The application forms depend entirely on the intended uses.

Mineral oil fractions having a medium to high boiling point, such as kerosene or diesel oil, as well as coal tar oils and oils of vegetable or animal origin, aliphatic, cyclic or aromatic hydrocarbons, e.g. benzene, toluene, xylene, paraffin, tetrahydronaphthalene, alkylated naphthalenes or derivatives thereof, for example methanol, ethanol, propanol, butanol, chloroform, carbon tetrachloride, cyclohexanol, cyclohexanone, chlorobenzene or isophorone, and strongly polar solvents, e.g. dimethylformamide, dimethyl sulfoxide, N-methylpyrrolidone and water, are suitable for the preparation of directly sprayable solutions, emulsions, pastes and oil dispersions.

Aqueous application forms can be prepared from emulsion concentrates, pastes, wettable powders or oil dispersions by adding water. For the preparation of emulsions, pastes or oil dispersions, the herbicidal active ingredient and/or the antidote, as such or in solution in an oil or solvent, are homogenized in water by means of wetting agents, adherents, dispersants or emulsifiers. However, it is also possible to prepare concentrates which consist, in addition to the herbicidal active ingredient and/or the antidote, of wetting agents, adherents, dispersants or emulsifiers and possibly solvents or oil and which are suitable for dilution with water.

Suitable surfactants are alkali metal, alkaline earth metal and ammonium salts of ligninsulfonic acid, naphthalenesulfonic acid, phenolsulfonic acid, alkylarylsulfonates, alkyl sulfates, alkylsulfonates, alkali metal and alkaline earth metal salts of dibutylnaphthalenesulfonic acid, lauryl ether sulfate, fatty alcohol sulfates, alkali metal and alkaline earth metal salts of fatty acids, salts of sulfated hexadecanols, heptadecanols and octadecanols, salts of sulfated fatty alcohol glycol ethers, condensates of sulfonated naphthalene and naphthalene derivatives with formaldehyde, condensates of naphthalene or of naphthalenesulfonic acids with phenol and formaldehyde, polyoxyethylene octylphenol ethers, ethoxylated isooctylphenol, octylphenol and nonylphenol, alkylphenol polyglycol ethers, tributylphenol polyglycol ethers, alkylaryl polyether alcohols, isotridecyl alcohol, fatty alcohol/ethylene oxide condensates, ethoxylated castor oil, polyoxyethylene alkyl ethers, ethoxylated polyoxypropylene, lauryl alcohol polyglycol ether acetal, sorbitol esters, lignin sulfite waste liquors and methylcellulose.

Powders, broadcasting agents and dusting agents can be prepared by mixing or milling the herbicidal active ingredient and/or the antidote together with a solid carrier.

Granules, for example coated, impregnated and homogeneous granules, can be prepared by binding the active ingredients to solid carriers. Examples of solid carriers are mineral earths, such as silica gel, silicas, silicates, talc, kaolin, attaclay, limestone, chalk, talc, bole, loess, clay, dolomite, kieselguhr, calcium sulfate, magnesium sulfate, magnesium oxide, milled plastics, fertilizers, e.g. ammonium sulfate, ammonium phosphate, ammonium nitrate and ureas, and vegetable products, such as grain flours, bark meal, wood meal and nutshell meal, cellulosic powders and others.

The formulations contain from 0.01 to 95, preferably from 0.5 to 90, % by weight of herbicidal active ingredient and antidote. The application rates of herbicidal active ingredient are from 0.05 to 5 kg of active substance (a.s.) per hectare.

The novel herbicides may contain, in addition to the substituted 2-aminothiophene I as the antidote and the herbicide from the group consisting of the (hetaryloxy)-or aryloxyphenoxyacetic acids II or of the cyclohexenones III, further herbicidal or growth-regulating active ingredients having a different chemical structure, the antagonistic effect being retained.

EXAMPLES OF BIOLOGICAL ACTION

The effect of various novel herbicides or herbicide combinations, consisting of the herbicide and the antidote, on the growth of desired and undesirable plants in comparison with the herbicidal active ingredient alone is demonstrated by the following biological examples from greenhouse experiments:

In greenhouse experiments, the culture vessels used were plastic flowerpots having a capacity of about 300 cm³ and containing loamy sand and about 3.0% of humus as a substrate. The seeds of the test plants were sown shallowly and separately according to species and were moistened. The vessels were then covered with transparent plastic covers until the seeds had uniformly germinated and the plants had begun to grow.

For the postemergence treatment, the test plants were first grown to a height of from 3 to 20 cm, depending on the form of growth, before being treated. The herbicides were suspended or emulsified in water as a distributing agent and sprayed by means of finely distributing nozzles.

The following was used as an example of the herbicidal cyclohexenone derivatives of the formula III: ##STR156##

For the postemergence treatment, all antidote compounds were prepared in a mixture consisting of 80% by weight of cyclohexenone as .a solvent and 20% by weight of a surfactant (Emulphor EL*)) with 10% by weight of active ingredient.

For comparison, the herbicidal active ingredient 12.42 was formulated as a 10-20% strength by weight emulsion concentrate and was used in the spray liquor in each case with the addition of the amount of solvent system with which the antidote compound was applied at the application rates shown in the Tables. The solution was prepared by mixing the active ingredient into a solution of 93% by weight of xylene and 7% by weight of Lutensol® AP-8**).

After application of the active ingredient mixture, the test plants were cultivated in a greenhouse, warmth-loving species at about 18°-30° C. and those from more temperate climates at about 10°-25° C.

The test period extended over from 3 to 5 weeks. During this time, the plants were tended and their reaction to the individual treatments was recorded.

The damage by the chemical agents was evaluated on the basis of a scale from 0 to 100% in comparison with the untreated control plants. 0 means no damage and 100 means complete destruction of the plants.

Table 16 documents the antidote action of the novel example compounds No. 14.14, 14.38, 15,014, 15.019, 15.020, 15,022, 15,027 and 15,062.
